The steady disappearance of Arctic sea ice, which is causing the exposed and darker surface of the Arctic Ocean to absorb more sunlight, is having a more profound impact on global warming than previously estimated, according to a new study.
The decline of albedo, or reflectivity, from the Arctic
A new modeling study by several geoengineering experts suggests that injecting aerosols into the atmosphere to block more of the sun’s energy and reduce temperatures could be most effective when done on a region-by-region basis.

As the summer melt season ends, Arctic sea ice extent has now fallen to an exceptionally low level, covering an area only half the size of the 1979 to 2000 average.
The Colorado-based National Snow and Ice Data Center (NSIDC) reported that as of September 16, Arctic sea ice extent was only 1.32 million square
